A people traffic jam that occurrs in subway tunnels and bus stations. Caused by inconsiderate workaholics walking too slow while their noses are glued to their Blackberry device.
I was late for work because there was a Blackberry Jam getting out of the A train.

When 3 or more people are in a meeting, not talking to each other, but are all checking, emailing or talking on their blackberries.
We had a few topics we needed to discuss in the departmental meeting, however it turned into a Blackberry Jam
